1. Expert bias: The Delphi technique relies on input from a panel of experts, which can introduce bias based on the individual perspectives and experiences of the participants. This can lead to inaccurate or skewed forecasts.
2. Lack of diversity: The panel of experts involved in the Delphi technique may not represent a diverse range of perspectives or expertise, leading to a limited understanding of the factors influencing demand for materials.
3. Time-consuming: The Delphi technique can be a time-consuming process, requiring multiple rounds of feedback and consensus-building among participants. This can delay the forecasting process and may not be feasible in situations where quick decisions are needed.
4. Cost: Engaging a panel of experts to participate in the Delphi technique can be costly, especially if they are required to dedicate significant time and resources to the process.
5. Limited scalability: The Delphi technique may not be easily scalable to larger organizations or complex supply chains, as it relies on a relatively small group of experts to provide input and make forecasts.
6. Lack of transparency: The Delphi technique can lack transparency in terms of how forecasts are generated and the rationale behind the final predictions. This can make it difficult to assess the accuracy and reliability of the forecasts.

Limitations of the Delphi Technique in Demand Forecasting:
1. Subjectivity and Bias:
- The Delphi technique relies on expert opinions, which can be subjective and biased. Experts may have vested interests or personal agendas that influence their estimates.
2. Time-Consuming and Expensive:
- The process involves multiple rounds of surveys, which can be time-consuming and expensive, especially for large-scale forecasting.
3. Groupthink and Convergence:
- Experts may experience pressure to conform to the majority opinion, leading to a lack of diversity in perspectives and a decreased likelihood of uncovering alternative scenarios.
4. Limited Representation:
- The selected experts may not fully represent the diversity of opinions within the organization or the wider market. This can result in biased forecasts.
5. Lack of Statistical Validation:
- The Delphi technique does not provide a statistical basis for forecasts. It relies on qualitative rather than quantitative data, which can limit its reliability and accuracy.
6. Difficulty in Quantifying Uncertainty:
- The Delphi technique does not explicitly address uncertainty in estimates. Experts may provide vague or overly optimistic forecasts, making it challenging to assess the risk associated with the forecast.
7. Lack of Iterative Feedback:
- The Delphi process typically involves only a few rounds of surveys. This limits the opportunity for participants to refine their estimates based on feedback from previous rounds.
8. Dependence on Expert Availability:
- The Delphi technique relies on the availability and cooperation of experts. If key experts are unavailable or uncooperative, it can compromise the quality of the forecast.
9. Cultural Influences:
- The Delphi technique can be influenced by cultural factors, such as the reluctance to express dissenting opinions or the tendency to avoid confrontation. This can hinder the free exchange of ideas.
10. Lack of Refinement:
- The Delphi technique may not be suitable for forecasting complex demand patterns or situations with significant volatility. It may require additional techniques, such as regression analysis or time series analysis, to improve forecast accuracy.
